WebDiesel Engines. Paul Breeze, in Piston Engine-Based Power Plants, 2024. Abstract. The compression ignition engine or diesel engine is the type that has most commonly been used for power generation, particularly in off-grid situations. The engine uses a higher compression ratio than a spark ignition engine to heat air in the engine cylinder. Fuel, … Electric sparks are used in spark plugs in gasoline internal combustion engines to ignite fuel and air mixtures. The electric discharge in a spark plug occurs between an insulated central electrode and a grounded terminal on the base of the plug. The voltage for the spark is provided by an ignition coil or magneto that is connected to the spark plug with an insulated wire.
